Example Embodiment

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] refer to figure 1 , the air pressure sensor assembly and the digital signal processor assembly constitute the two basic functional modules of the air data computer of the present invention, which are the basic configurations of the present invention. The airflow direction sensor can be used as an optional accessory for users, and on this basis, GPS receiver components can also be added, including GPS receiving antenna, high-frequency feeder cable and GPS receiver board.

[0022] The total pressure tube, the static pressure tube, the temperature sensor and the airflow direction sensor are all installed on the outside of the aircraft, wherein the total pressure tube is a metal tube with an opening facing the flight direction of the aircraft, and the static pressure tube is a metal tube with an opening towards the side or rear of ...

Abstract

The invention discloses an air data computer, which comprises an air pressure sensor assembly and a data signal processor assembly, wherein the air pressure sensor assembly comprises a full pressure sensor, a static pressure sensor and a first microprocessor, the digital signal processing assembly comprises a second microprocessor, and the second microprocessor receives the static pressure data and movable pressure data output by the air pressure sensor assembly and the actual measurement temperature data output by a temperature sensor at time intervals through gating signals for calculating air data. The air data computer has the advantages that the size is small, the weight is light, the power consumption is low, the data processing speed is high, and the low air pressure altitude data hop amplitude is small.

Description

technical field [0001] The invention belongs to the field of avionics, and more specifically relates to an air data computer system and its realization method. Background technique [0002] The air data computer is used for the control and navigation of aircraft flight, and can provide the aircraft with total atmospheric temperature data, atmospheric static temperature data, atmospheric static pressure data, atmospheric total pressure data, barometric altitude data, true air speed data, indicated air speed data, Mach Airflow direction, ascending and descending speed and relative altitude data, these data are collectively referred to as atmospheric data. [0003] Among them, the total atmospheric temperature refers to the atmospheric temperature at the stagnation point after the atmosphere is compressed during the flight of the aircraft; the static atmospheric temperature refers to the undisturbed atmospheric temperature around the aircraft during flight; the static atmospher...
